Screw Mounting

1.

Pull out the two hooks on the back of the Relay to the outside until 

you hear them click in place.

2.

Insert M3 screws into the hook holes and secure the Relay.

Adjusting the Setting Knobs

• Use a flat-blade screwdriver to adjust the setting knobs. The knobs 

have a stopper that prevents them from turning beyond the full right 
or left position. Do not force a knob beyond these points.

• To reduce the error in the setting knob, always turn the setting knob 

from the minimum setting toward the maximum setting.

Connecting Wires to the Push-In Plus Terminal Block

Part Names of the Terminal Block

Connecting Wires with Ferrules and Solid Wires

Insert the solid wire or ferrule straight into the terminal block until the 
end strikes the terminal block.

If a wire is difficult to connect because it is too thin, use a flat-blade 
screwdriver in the same way as when connecting stranded wire.

Connecting Stranded Wires

Use the following procedure to connect the wires to the terminal block.

1.

Hold a flat-blade screwdriver at an angle and insert it into the 

release hole. The angle should be between 10° and 15°.

If the flat-blade screwdriver is inserted correctly, you will feel the 

spring in the release hole.

2.

With the flat-blade screwdriver still inserted into the release hole, 

insert the wire into the terminal hole until it strikes the terminal block.

3.

Remove the flat-blade screwdriver from the release hole.

Checking Connections

• After the insertion, pull gently on the wire to make sure that it will 

not come off and the wire is securely fastened to the terminal block.

• If you use a ferrule with a conductor length of 10 mm, part of the 

conductor may be visible after the ferrule is inserted into the 
terminal block, but the product insulation distance will still be 
satisfied.

Removing Wires from the Push-In Plus Terminal Block

Use the following procedure to remove wires from the terminal block.
The same method is used to remove stranded wires, solid wires, and 
ferrules.

1.

Hold a flat-blade screwdriver at an angle and insert it into the 

release hole.

2.

With the screwdriver still inserted into the release hole, remove the 

wire from the terminal insertion hole.

3.

Remove the flat-blade screwdriver from the release hole.
